Question

The water is leaving the nozzle of a hose with a volume flow
rate of 0.50 m^{3}/s. Assume there are no leaks and the
nozzle has a circular opening with diameter of 4.5 mm.

**1) How fast is the water leaving the nozzle of a
hose? (Express your answer to two significant
figures.)**

**Note: 31453.96 is NOT the correct
answer**

Answer #1

. The nozzle of a garden hose is shown to the right. The hose
has a v1 v2 diameter of 2.5 cm, and the opening on the right has a
diameter of
0.75 cm. The water emerges from the opening to the air, so it is
at
atmospheric pressure. If the speed of the water at the opening v2
is
15 m/s,
A) What volume of water emerges from the hose every minute?
(Express your answer in gallons, where

The
hose has a diameter of 2.5 cm, but the nozzle has a diameter of
only 1.10 cm. The water that comes out of the hose fills a
container of 25 Len 1.50 min. Calculate: a- the volume flow flowing
through the hose b- the velocity of the water leaving the nozzle c-
if the pressure external to the hose is atmospheric, what is the
absolute pressure of the water inside the hose?

Question 3. A garden hose attached with a nozzle is
used to fill a 25-gal (1gal =3.785L) bucket.
The water flows in the hose with the inner diameter of 1.1 in, and
exits at the nozzle at 50 m/s of
velocity. If it takes 0.8 min to fill the bucket with water,
determine
i. the volume and mass flow rates of water through the hose,
ii. the inner dimeter at the nozzle exit?
iii. the kinetic energy changes through the...

Calculate the Reynolds number for the flow of water to a nozzle
with a radius of 0.270 cm in a garden hose with the radius of 0.950
cm when the nozzle is attached to the hose the flow rate through
hose and nozzle is 0.490 L per second assume the temperature of
water is 20°C
A. a nozzle with the radius of 0.270
Can the flow be laminar
B. A garden hose with the radius 0.950 cm
Can the flow...

1. In a turbo jet engine, the momentum of the gases
leaving the nozzle produces the propulsive force. The enthalpy and
velocity of the gases at the nozzle entrance are 1200 kJ/kg and 200
m/s respectively. The enthalpy of the gas at exit is 900 kJ/kg. If
the heat loss from the nozzle is negligible, determine the velocity
of the gas jet at exit from the nozzle.
2. For question 1, if the diameter of the nozzle at
exit is...

Water flows at the rate of 3.48 kg/s through a hose with a
diameter of 3.00 cm.
(a) What is the speed of water in this hose?
(b) If the hose is attached to a nozzle with a diameter of 0.750
cm, what is the speed of water in the nozzle?
(c) Is the number of kilograms per second flowing through the
nozzle greater than, less than, or equal to 3.48 kg/s?

A firefighter mounts the nozzle of his fire hose a distance 36.9
m away from the edge of a burning building so that it sprays from
ground level at a 45° angle above the horizontal. After quenching a
hotspot at a height of 9.45 m, the firefighter adjusts the nozzle
diameter so that the water hits the building at a height of 17.1 m.
By what factor was the nozzle diameter changed? Assume that the
flow rate of water through...

Water flows at 3.9 m / s through a garden hose of a diameter of
2.10 cm and emerges from a nozzle of a radius of 0.56 cm. If the
nozzle is directed vertically upward, to what height would the
water rise? Give your answer to two decimal places and remember add
unit m after the numerical value.

A jet of water falls vertically through the air. Upon leaving of
the pen, it is a jet with a circular section of 1.0 cm diameter and
comes out with a speed of 20 cm / s. In a point 10 cm below, (a)
how fast is the jet and (b) what diameter is its cross section? Use
the flow laws.
